On this site, you will find information for monitoring emergency services, public safety, and law enforcement agencies in Somerset County, New Jersey and select surrounding cities / boroughs / townships outside its borders. Gaining functionality to this service is easy: either just stay on the page and listen to the player embedded in it OR download the Win500 Remote Monitoring Client below, extract the files to wherever you please, run the program and enter the parameters!
The difference between using your internet browser and using Win500 is that with Win500, you can view in real-time the channels that are talking, as opposed to just hearing plain audio.
